Hi All, my 1999 LS400(107k miles) recently got a CEL. Pulled the codes: P0161 O2 Sensor Heater Circuit Malfunction, Bank2 Sensor2. I've searched this forum and cannot find anyone that has this code. I've seen other model Lexus's with this CEL but not LS400s.

Is Bank2Sensor2 on the passenger side after the Cat?

Which O2 sensor do I buy from OxygenSensors.com? Post-Cat right, or Post-Cat left?

Does anyone have pics of how to change this sensor? I'm very leary about pulling up the carpet if necessary. I even read somewhere that the center console has to be removed! Is that true?

Thanks!!!!!

Nevermind, I just saw that the part numbers are the same for both right, left pre-cat and both right, left post-cat.
